Anzu wyliei or the "feathered demon" was a very large oviraptor that lived in the upper Cretaceous period (Hell Creek Formation), and was formally described in 2014. Anzu was nicknamed the "Chicken from Hell" since it is among the largest feathered dinosaurs ever found in North America. This dinosaur is characterized by a toothless beak, long arms ending with large claws, and long powerful legs. This raptor was most likely an omnivore feeding on small animals, vegetation, and possibly eggs. The late Cretaceous specimens grew to 13 feet and 600 pounds. Fossil remains include well preserved bones and large claws. Their large claws are highly prized by collectors and they are among the best dinosaurs claws available. These top quality specimens were all legally collected from private lands in the northwestern US. Late Cretaceous, Hell Creek Fm. (or equivalent), 66 MYA.
1. These claws are the fossilized bone core of the actual claw. The bone core would be covered with a keratin or (a nail-like substance) that would increase the length by a minimum of 50%. Anzu had big, sharp claws!
